The answer is mitochondrion. Mitochondria are critical for the cell’s biochemical processes that require energy to be powered. Mitochondria are responsible for generating this power in the form of ATP through a process called chemiosmosis. Without ATP, the cell would immediately die since it would be incapable of performing virtually all biochemical processes that re required to sustain life.
Answer:
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby.
Answer:
And so, an endothermic vertebrate is an animal that can produce its own heat and possesses a spinal backbone consisting of vertebrae. Examples of these organisms include most mammals (including humans), most birds, and some reptiles.
Explanation:
Ectothermic vertebrates are, for example, fish, amphibians and reptiles. Their temperature depends on the environment. The contrary to ectothermic are endothermic vertebrates, such as birds or mammals
Answer:
<em>Astrocytes</em>
Explanation:
In the central nervous system, astrocytes, also collectively known as astroglia, are distinctive star-shaped glial cells.
It is not well known the ratio of astrocytes in the brain.
Research has found that the astrocyte proportion varies by area depending on the counting technique used and varies from 20% to 40% among all glia.
These fulfill many roles, namely <em>biochemical reinforcement of tumor cells that build the blood-brain barrier, nutritional supply to the nervous tissue, extracellular ion balance maintenance, as well as a function in the brain and spinal cord repair and scarring cycle after severe injuries.</em>
<span>Blood pH decreases
For this problem you need to remember what pH is. The higher the molarity of hydrogen ions, the lower the pH, or the more acid the solution is. The lower the molarity of hydrogen ions, the higher the pH, or the more basic the solution is. Now consider the question. You're having fewer hydrogen ions being secreted into the filtrate. That means that the substance being filtered has it's hydrogen ion concentration increasing. And the substance being filtered is blood. And since the hydrogen ion concentration is increasing, the pH is decreasing. So the answer is "Blood pH decreases".</span>
